A boiler needs sufficient water pressure to function properly.
When the water pressure gets too low, the boiler may heat less well or show a fault. In many cases, you can top up the installation yourself easily.
When should I top up my boiler?
Most boilers work well at a water pressure of roughly between 1.5 and 2.0 bar.
When the pressure is clearly lower, it may be necessary to top up water.
You can check the water pressure on the display or the pressure gauge of your boiler.
What do you need?
For topping up, you generally need:
- A filling hose.
- A tap to top up the installation.
- A cloth or towel for any residual water.
The exact procedure can differ per installation.
How do I top up my boiler?
Broadly, this works as follows:
- Check the current water pressure.
- Connect the filling hose to the filling points.
- Carefully open the filling valve.
- Fill the installation until the correct pressure is reached.
- Close the filling valve and check the installation.
Always follow the instructions for your specific boiler. The exact steps can differ per brand and model.
